General Requirements: a. Horizontal lifelines shall be designed and installed, under the supervision of a Qualified Person, as part of a complete personal

Fall Protection system. b. c. d. e.

The horizontal lifeline must be level (less than a 5% grade).

Engineers shall, at minimum determine the performance of the system when a fall occurs on the shortest span (largest forces) and the longest span (largest total fall distance) in the system.

Evolution tip over posts and/or energy absorbers shall not be used to limit the maximum arrest force of the worker. The Evolution tip over posts and/or energy absorbers shall be used only to control or reduce the maximum arrest load on the structure.

Anchorages for horizontal lifelines systems shall be verified and designed, prior to use, by a Qualified Person with experience and trained in designing and using horizontal lifelines systems.

4. f. g.

HLL(s) shall satisfy the seismic conditions for nonstructural components as described by ASCE/SEI 7 and the most current edition of the IBC. No exceptions can be taken if the system is required to function for life-safety purposes after an earthquake.

The fall arrest system shall consist of a stainless steel safety cable attached to the structure. The cable shall be continuous or shall have swaged splices, which allow the user to pass without disconnecting from the system. h. i.

Restraint HLL(s) shall be designed per ANSI Z359.2 & ANSI Z359.6: a. The HLL(s) shall prevent workers from reaching and falling into any open hole or off the edge of a working surface. b.

Brackets and supports shall be attached to the structure with appropriate anchors of proper size to adequately support the intended loaded.

The HLL(s) shall comply with the manufacture’s design requirements. c.

The horizontal lifeline shall comply with the requirements for fall arrest horizontal lifelines as indicated in this document.

Where a worker is using a full body harness the force on the worker’s body shall not exceed 400 lbs. d. e.

Evolution tip over posts and/or energy absorbers may be used in travel restraint systems; provided that the engineer has determined that the restraint forces will not cause the tip over posts and/or energy absorbers to deploy and ensures that the deflection of the wire rope in combination with other deformations of the restraint system will not permit the worker(s) to reach the fall hazard.

The use of fall restraint systems shall be limited to surfaces at or less than a slope of 4:12 from the horizontal. This is so a fall will not result in dynamic loading on the fall restraint system or where the authorized person could end up being suspended vertically from the system.

Fall Arrest HLL(s) shall be designed per ANSI Z359.2 & ANSI Z359.6: a. The selection, design, and installation of fall arrest horizontal lifelines shall be performed under the supervision of a Qualified

Person.

4/10/2020 XXXXX - 5



1.6 b. c. d. e.

Fall arrest horizontal lifelines shall have the strength capable of sustaining static loads applied to the wire rope of at least two times the maximum arresting force.

When more than one user is attached to a horizontal lifeline, the load on the lifeline can be determined using either lumped mass or sequential fall as described in ANSI Z359.6 [6.3.6]

The swing fall shall comply with ANSI Z359.6 [5.3]

The clearance safety margin shall comply with ANSI Z359.6

[7.2.6.2]

ANSI Z359.14

C. Horizontal lifelines shall be used exclusively for their designed use and shall be marked to prevent other uses.

D. The design shall take into consideration the potential uses of and loads on the horizontal lifeline, in order to facilitate the prompt rescue of workers who may fall while attached to the system.
